There seem to be as many 322s as ever on the Wharfedale Line: of 8 journeys I took last week, 3 turned out to be 322s (one Ilkley–Bradford, one Bradford–Ilkley, and one Ilkley–Leeds), all of which were shown on Realtime Trains as “Pathed as Class 333 EMU” — and at least the Leeds journey being one that's usually a 333.
This morning there was a broken down 322 clogging up platform 2 at Ilkley, and the train I was on crossed with another 322 at Guiseley (I think the 09:02 from Leeds, which apparently spent
19 minutes on the platform at Guiseley).
I think I've only seen one 331 this year, and I haven't been on one for months.
